JACOB NZ. PHILLIPS, OB PILLOW, PENNSYLVANIA PUMP Application filedNovember 4-, 1929. Serial No. 404,702.

. This invention relates toa hydrostatic' amp, the general object of theinvention eing to provide means whereby the operation of a'piston in acylinder located at any 6 point outside of the well will operate meansinside the well for raising water from the well, the cylinder beingconnected to the means in the well by a pipe, thus avoiding the usevof apump) rod and enabling the'op e placed in a dwelling or v erating meansto the like a distance from the well, thus avoiding the use of aseparate pump house over the well.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described,

illustrated'in the accompanying drawing and specifically pointed ,out inthe appended 9 claim.

in describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the sev- 5 eral views, and in whichFigure 1 is a diagrammatic view, partly in section, showing one form ofthe invention.

Figure 2 is a'sectional view showinga 3 modification.

Referring to Figure 1, the numeral 1 indicates a cylinder having apiston.2 therein, the rod 3 of which is reciprocated through any desiredmeans, the drawings showing -the rod being connected by a crank 4 to a.

driven shaft 5 which may be rotated by hand or power. A delivery pipe 6is connected with the top of the cylinder and has a check valve 7therein and a branch pipe 8 connects this pipe 6 with the bottom of thecylinder, a spring pressed valve 9 beingarranged in this branch pipe,the spring of which can be adjusted by means of the handle 10.

A pipe 11 connects the bottom of the cyl inder 1 withthe top of acylinder 12 located in the well, the feed pipe of said cylinder 12 beingshown at 13, and this pipe has a checkvalve 14 therein. A ,pipe 15connects the upper end of the pipe 13 with the bottom of a pressurechamber 16 and a branch pipe 17 connects the upper part of the pipe 15with {the lower part or the pi e 11. A check valve 18 is arranged inthis ranchpipe. A piston 20 is arranged in the cylinder 12 and assspring 21 connects the upper end 'of the piston rod with the top of thecylinder, this spring tending to hold the piston against a spider 22laced in the cylinder 12. 4 i

n the down stroke of the piston 2, the water in cylinder 1 and pipelland the upper part of cylinder 12 will be placed under pressure sothat the piston 20 willbe pushed downwardly and during. this action, the

valves 14 and 18 are closed; The downward 66 movement of the piston 20forces water from the bottom of the cylinder 12 past the check valve 23in the lower part of pipe 15, through I the pipe 15 into the pressurechamber 16, compressing the air in said chamber.- The down- 70 wardmovementof the piston 2 creates a partial vacuum in the upper part ofthe cylinder lwhich causes thevalve 9 to open so that some of the waterin cylinder 1 will pass through the pipe 8 into the upper part of thecylinder 1. On-the up stroke of the piston, 2, the partial vacuumcreated in the lower part of the cylinder 1 will reduce the pressure inpipe 11 so that the air in the air chamber will force the water in saidchamber through the branch 17 into the pipe 11, from which the Waterpasses into the cylinder 1 as the piston vl0.moves upwardly. Thereduction of pressure in the pipe 11 also permits the spring 21 to raisethepiston 20 and the partial vacuum created by the upward movement ofthe piston :20 draws water through the pipe 13 into the lower part ofthe cylinder 12. As the piston 2 moves upwardly, the water in the upperend of the cylinder 1 is forced through the pipe 6 past the valve7 tothe point of use.

- Thus itwill be seen that the reciprocation of the piston 2 will resultin the'vibration or reciprocatory movement of the piston 20 so thatwater is alternately drawn into the lower part of the cylinder 12 andthen forced into the pressure chamber 16 and the compressed air in saidchamber. will force this water through the pipe 11 into the cylinder 1on each up stroke of the piston 2 and the move ment of the piston 2 willcause the water to pass from the cylinder 1 to the point of use,

In the modificationshown in Figure 2, the pressure chamber 16' is formedon the top of the cylinder 12, with the pipe 15 and the branch 17 formedintegral or suitably connected with the parts and the lower part of thepipe 11 passing through the compression chamber. In other respects, thisform of the invention is the same as that before described.

This invention provides a pump system which is inexpensive tomanufacture and install, one which can be used to pump from differentwells at the same time and as it eliminates a pump rod, the operatingparts outside of the well can be placed in a dwelling or the like adistance from'the well so that a separate pump house is not needed. Byplacing the cylinder 1 in the dwelling, in

20 the kitchen, for instance, it is not necessary to carry water fromthe pump to the engine.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claim.

What I claim is 4 A pump system comprising a cylinder, an imperforatepiston therein, means for operating the piston, a pipe connected withthe top of the cylinder and having a check valve therein, a branch pipeconnecting said pipe with the bottom of the cylinder, a spring pressedvalve in the branch pipe, means for adjusting the tension of the springthereof, a second cylinder, a pipe connecting the bot- I tom of thefirst cylinder with'the top of the second cylinder, an imperforatepiston in the second cy'linder,-a spring connecting the ia-- ton rodthereof with the top of the cylinder and tending to hold the piston inraised position, a well pipe connected with the bottom of the secondcylinder and having a check valve therein,a compression chamber, a pipeconnecting the same with the well pipe and a pipe connecting the pipewhich is connected with the compression chamber with the pipe whichconnects the'two cylinderstogether, sald pipe containing a check valve.

In testimony whereof I aflix my signature.

JACOB MILTON PHILLIPS.-
